In the meanwhile, this type of fish can be found in 45 countries worldwide. In addition, it has won repeatedly numerous lakes.

In addition to the reddish side strips, their color may vary widely from a dark bluish-green or olive-green while the stomach is whitish. Black spots, which cover the entire body except the bottom, are typical physical characteristic. In average, this fish is long between 35 and 50 cm and weights around one kilogram. However, there have been some examples of the ones, which were 120 cm long and 20 kilograms heavy.

Generally, trout prefer running water with low temperatures, but they can also be found in the lakes and similar stagnant water tanks, where they often remain in medium depths.

As juvenile fishes, they live in flocks, but after they reach the weight of three kilograms, they become individual. They are good hunters who impress with their speed and agility. In the wildness, they feed on insects, small amphibians, crayfish, worms, snails and small fishes. In our aquacultures, they are fed with a high-quality fish pellets.
